The San Francisco Chronicle reports:

San Francisco Mayor Gavin Newsom announced today a moratorium on official city travel to Arizona after the state enacted a controversial new immigration law that directs local police to arrest those suspected of being in the country illegally.

Could we build a dome over that city? How is forcefield technology coming along? Or maybe we could get all these jailed illegal immigrants to dig a big moat around the place? Dos pájaros, una piedra.
